Each solid microneedle is formed by a molding process and the microneedle has body with first (30) and second cavities (40) extending therein. The hollow microneedles are formed by removing a portion of the polymeric material disposed between the first cavity and the second cavity. A method for determining the location of a microneedle in an article comprising solid microneedles is also provided. The method comprises directing electromagnetic radiation toward an article comprising a plurality of microneedles and imaging the article.

Abstract: An optical system includes a lens layer including a plurality of microlenses arranged along orthogonal first and second directions, and at least one optically opaque mask layer spaced apart from the lens layer and defining a plurality of through openings therein arranged along the first and second directions. There is a one-to-one correspondence between the microlenses and the openings, such that for each microlens, the microlens and corresponding openings are substantially centered on a straight line making a same oblique angle with the lens layer. An optical layer can include the lens layer and the optically opaque mask layer embedded in the optical layer.

Abstract: An exposure system includes a light source emitting a beam along an optical axis that is capable of inducing a multi-photon reaction in a resin. The exposure system further includes a resin undergoing multiphoton reaction, as well as an automated system including a monitor that measures at least one property of the beam selected from power, pulse length, shape, divergence, or position in a plane normal to the optical axis. The monitor generates at least one signal indicative of the property of the beam, and a sub-system adjusts the beam in response to the signal from the monitor.

Abstract: An optical construction includes a lens film having outermost first and second major surfaces. The first major surface includes a plurality of microlenses. A multilayer mask having an average thickness of less than about 0.5 times an average focal length of the microlenses and an optical density of greater than about 2 is disposed on the second major surface. The multilayer mask includes polymeric first and second mask layers where each of the first and second mask layers has an optical density of greater than about 0.3. The multilayer mask defines a plurality of laser-ablated through openings therein that are aligned to the microlenses in a one-to-one correspondence. An optical transmittance of the optical construction as a function of the incident angle has a transmitted peak having a peak transmittance T1 and a corresponding full width at 20 percent of maximum W1, where T1/W1≥2.4%/degree.

Abstract: An optical construction includes a lens layer and optically opaque first and second mask layers. The lens layer has a first major surface including a plurality of microlenses arranged along orthogonal first and second directions. The first and second mask layers are spaced apart from the first major surface and define respective pluralities of through first and second openings therein arranged along the first and second directions. The first mask layer is disposed between the structured first major surface and the second mask layer. There is a one-to-one correspondence between the microlenses and the first and second openings. The optical construction includes an intermediate layer disposed between the structured first major surface and the first mask layer and including an undulating second major surface facing, and in substantial registration with, an undulating third major surface of first mask layer so as to define a substantially uniform spacing therebetween.

Abstract: The present disclosure provides engineered surfaces that exhibit reduced specular reflection and gloss while still providing a high intensity of reflected light at multiple incident angles. The structured metal surfaces include engineered topography that increases diffuse reflection, leading to a greater intensity of light perceived at multiple viewing angles. A viewer engaging such surfaces is likely to perceive a stronger ‘white’ reflection of the incident light and an improvement, particularly in orthodontic and other oral applications, of aesthetic appearance. Methods of creating the engineered surfaces and orthodontic articles incorporating the engineered surfaces are also disclosed.

Abstract: Provided are adhesive-backed films and related methods useful in laser cutting a substrate protected by an adhesive-backed film. The adhesive-backed film includes a base layer comprised of a polymer and having opposing first and second major surfaces and an adhesive layer comprising a pressure-sensitive adhesive directly or indirectly coupled to the second major surface. An infrared absorber is present in one or both of the polymer and the pressure-sensitive adhesive, and the adhesive-backed film is sufficiently transparent to enable visual inspection of a surface having the adhesive-backed film disposed thereon.
